摘要： A Cherenkov imaging system for determining surface radiation dose for a subject undergoing radiation therapy includes (a) a first camera for capturing a Cherenkov image of Cherenkov radiation from a surface region of the subject undergoing Cherenkov-radiation-inducing radiation therapy, (b) a second camera for capturing a reflectance image of reflectance of optical illumination off the surface region, and (c) a correction module for correcting the Cherenkov image based upon the reflectance image to form a corrected Cherenkov image that indicates radiation dose for the surface region. A Cherenkov imaging method for determining surface radiation dose for a subject, undergoing radiation therapy includes correcting a Cherenkov image, of Cherenkov radiation from a surface region of the subject undergoing Cherenkov-radiation-inducing radiation therapy, using a reflectance image of visible light reflected by the surface region, to form a corrected Cherenkov image that indicates radiation dose for the surface region.
